Data logging can be set for single point or continuous logging. Single data points as well as statistics (Max, Min, Average) can be stored in the built-in memory and recalled to the display. Often users need to adjust machinery during testing, with the DT-2100 you can mount it on a tripod, select continuous logging and adjust machinery as necessary.
